Laser-Induced Holographic Surface Relief Gratings on Nonlinear Optical Polymer Films.
Abstract
We report observation of holographic surface relief gratings with relatively large amplitude on a second order nonlinear optical polymeric material. Surface relief gratings on these polymer films were created upon exposure to polarized Ar+ laser beams at 488 nm without any subsequent processing steps. The surface structure of the relief gratings was investigated by atomic force microscopy. The depth of the surface relief in a typical case was 140 nm which is approximately 25% of the original film thickness. Diffraction efficiency of gold-coated gratings were investigated as a function of wavelength and capability of recording orthogonal gratings on the same film was demonstrated. (MM)
